A method is described for selectively etching photoresist on a semiconductor substrate having one or more layers of a spin on glass, including an edge bead that was formed when the glass was originally applied. First the wafer is coated with a layer of unexposed, undeveloped negative photoresist. Then, while spinning the wafer, a vertical jet of photoresist EBR solvent is directed to a point just inside the edge so that photoresist gets removed from an annular area extending inwards from the perimeter. The edge bead is then removed using a liquid etchant and integrated circuit processing can now proceed, making use of the unexposed, undeveloped layer of photoresist in the usual way; that is, exposing it through a mask and then developing and baking it before using it as an etch mask. The method is general and may be used in other situations where selective removal of photoresist along the periphery is required and where the remaining resist is to be used for other purposes.
